Adjustable Drip Emitter on Barb 360-Degree

In Stock

The 0-10 GPH adjustable drip emitter on barb with 360-degree flow pattern produces a gentle stream pattern that can be adjusted from small to large coverage. Available with barb or spike, this drip emitter is used to water an individual plant or group of plants.

The 180° and the 360° adjustable flow drip emitters have a flow range of 0 to 10 GPH at a preset pressure of 25 PSI. When the cap is rotated the adjustable drip emitter flow and the radius of the soaked area change from a drip to a gentle stream pattern to off. This feature allows the user to adjust the flow to each individual plant as needed. Twisting the dial on the drip emitter towards the "+" or the "-" signs allows the user to increase or decrease the flow rate. Our range of adjustable drip emitters come with 5" spike and 1/4" side barb inlet or with 1/4" barb inlet only. The ideal use for this range of adjustable drip emitters is for a group of plants or under a large individual plant.

We have a lot of calcium in our water, and I've found that these emitters will clog when set to their lowest settings. They work better for me when the drip rate is set to a stream rather than a drip. Not the fault of the emitter, but something to be aware of.

I bought these initially thinking that they would be used for some small trees and large shrubs. But over time, I found that the adjustable 180 deg. sprayers do a better job for my purposes. If you had an entirely drip-irrigation setup, I can see these being more effective. When combined with sprayers, the water flow rate is too different and the trees get underwatered.

I used the D031 to replace another brand in my peach orchard. The other brand was constantly plugging with carbonate minerals in my well water. The D031 is working much better, not plugging, watering more uniformly, allowing for less time per cycle.

Installation for Adjustable Drip Emitters

When using this type of drip emitter be aware that as you adjust the flow, the total flow rate of the system may be affected and this may lower the system uniformity. In other words, increasing the flow from each adjustable drip emitter on your system may limit the efficiency of the system. For example, on 1/4" micro tubing only three to four adjustable drip emitters should be used when they are opened to the maximum flow, and it is recommended to use no more than 20 to 25 adjustable drip emitters on 1/2" drip tubing.
